The rib cage also contains muscles with an expiratory action. These are the internal intercostal muscles, which slope backward; contraction causes the ribs to move downward and inward, similar to the lowering of a bucket handle.Both internal and external intercostal muscles are also involved in flexing and twisting the trunk.Read more about Breathe Strong, Perform Better.ntercostal muscle contraction also brings about stiffening of the rib cage during lifting, pushing, and pulling movements, which makes the intercostal muscles an important contributor to these movements.
Intercostal Strain. In the spine there is an intercostal muscle group consisting of the internal and external intercostals, and the subcostal and transverse thoracic muscles, located between the ribs in the thoracic cavity.These muscles can become strained due to rapid movements that bend or twist the upper body suddenly.s a result the incidence of muscle injury to the thoracic spine is lower, however it is still possible to experience strain of the intercostal muscles. The muscular system of the spine is large and complex, including the deep erector spinae or paraspinal muscle groups that run parallel to the spine.
